Primary Examination

The next Primary Exam is scheduled for March 9, 2018

The ABNS Primary Examination is an important step in the certification process. It is available to all residents in ACGME accredited neurosurgery programs and is designed to evaluate candidates’ knowledge and provide direction for continued learning. Residents may take the exam for self-assessment or for credit toward certification as determined by their program director. The ABNS prepares the 375 question examination with the guidance of the National Board of Medical Examiners (NBME). The exam is given each March at most U.S. neurosurgical residency programs. The ABNS and RRC require residents to pass the Examination for credit toward certification before completing training. Many Program Directors require passage before the chief year.

Neurosurgeons who completed residency training in ACGME accredited programs may take the Primary Examination as often as they wish. Individuals who entered Canadian neurosurgery programs prior to July 16, 1997 may also take it. ABNS Rules and Regulations do not allow it to be offered to fellows or medical school students, etc.
